SIPHvQN-HEAD.

SPECIFICATION forming part of Letters Patent No. 602,2Q0, dated April 12, 1898.

Application led J une 11,1897. Serial No. 640,321. (No model.)

T0 a/ZZ whom it may concern:

Be it known that I, EMIL SINGER, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Siphon-Heads; and I do herebydeclare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to the top .or valve mechanism of so-called siphon-bottles or such as are used for carbonated mineral waters in which the pressure of the carbonicacid gas with which the beverage is charged is the means by which the liquid is expelled through the spout when the valve is open, and has for its object to enable the valve'of the head to be removed without disturbing the connection between the head and the bottle.

More particularly my invention relatesY to the construction and combination of parts, whereby when the valve is open direct communication is formed with the spout through a cavity or channel arranged longitudinally within the top piece.

My invention consists, essentially, of an inwardly-extending tube open at both ends and threaded on its inner surface, a cap for closing its outer end and the inner end 0f the tube provided with an open flange through which a valve is purposed to protrude, having a circular flange abutting with the inner surface of the open flange on the tube, and a supplemental tube having an open flange on one end and provided with slots in the periphery of the outer end for the insertion of a tool for screwing it into the inwardly-extending tube, the flange on the supplemental tube pressing tightly against the -flange of the valve which -bears against the open flange on the tube, stopping all leakage through the tube in which the valve-stem fits, a washer formed on the valve-stem and a spiral spring surrounding the stem and bearing against the washer, and a cap for closing the end of the supplemental tube purposed to bear up against the spring for tightening the pressure of the valve in the opening to the spout; also, the construction of the valve-lever, pivoted to an arm extending up from the outer surface of the top piece, the lever extending down through an opening in the top piece and inserted in the slot in the valve-stem, and of otherdetails of construction hereinafter more particularlypointed out in the drawings.

That myinvention may be more fully understood reference is had to the accompanywa detail of the valve and stem.

In the drawings, A is the bottle, and B the ordinary glass tube, reaching down nearly to the bottom. of the bottle and through which vthe liquid is pressed up to the spout by the `pressure of the gas within the bottle.

The tube B is provided at its upper end with the usual flanged top or fitting b of soft metal, the

upper end of which fits in a corresponding recess in the lower end of the top piece C, which latter is united to the bottle by being threaded and screwed down upon the threaded ring a, made of two semicircular pieces, which embrace the bottle-neck and are retained by the shoulder on the bottle-head, as usual. A packing-ring b makes a tight joint between the top piece C, the flangedy piece b, and the upper end of the bottle simultaneously.

In line with'the glasstubel have provided, in the lower surface of the top piece C, an opening that opens into a cavity c, arranged longitudinally within the top piece,and in one end of the said cavityis formed theinnerend of the opening fa of the spout c'. The top C is made tubular in form and is open at one end. D is a cap fitting over the open end. Extending from the open end to a point near the 'opening to the spout I have shownran inwardly-extendingtubeE, threaded on its inner surface and provided with an open circular flange, as at e.

F is the valve, preferably made of rubber, but may be made of any elastic material that will serve the purpose, having the shap'e of a ball for fitting in the inner end of opening n of the spout and having the extended circular flange f, which is purposed to be carried in the tube E and to bear up against the flange e. I have provided a bearing-surface for the iiange of the valve to insure the pressure being uniform when the valve is opened.

IOO

g2 is a wire cast in the valve surrounding the inside of the liange and near its outer circumference, by which means I am able to keep the valve-head in `place between the flanges of the tubes.

G is the valve rod or stem, to which the rubber valve is secured in the manner shown in Fig. 2, and g is a washer integral with the stem Q, the stem being also provided with the slot g I-I is a supplemental tube screwed into tube E and brought to bear against the flange f of the valve F, this tube being provided with slots f in its peripheral face at the rear for the purpose of inserting a tool for screwing it into or out of the tube. Carried in the su pplemental tube and surrounding the spindle I have shown an ordinary spiral spring I, bearing against the washer g on the stem,

purposed to press or tighten the valve F against its seat directly upon the spout-opening n. This is accomplished through and by means of the cap J, which is threaded around its circumference, purposed to be screwed into the rear end of the tube II and abutting with the spring. By providing a head of the character shown in the tube I-I, I am able to take up any slack in the spring and insure a complete closing of the valve.

I have shown extending up from part C the arm K, having the loop 7c.

L is a lever to open the valve for drawing liquid from the bottle and is pivoted at Z to the arm K, as shown in Fig. l, and is inserted through the slot s in the upper face of top part C, then through the slot g in the spindle G.

In putting the parts together the valve F is iirst inserted in the inwardly-extending tube E of the top piece O and brought to bear in the opening n of the spout. The supplemental tube I-I is then screwed into the tube E, the fiange of the tube I-I contacting with the liange on the valve which abuts with the fiange on the tube E. The spiral spring I is then put into place around the stem of the valve. The cap J is screwed into the supplemental tube, forcing the valve into contact with the opening n in the spout. lever L is dropped into the slot in the spindle through the opening in the casin g and pivoted to arm K. The cap D is then placed in position, closing the opening through which the parts have been inserted. By this means I am enabled to remove the valve-head and its auxiliary parts without in any Way inter- The tering with the connection between the top piece and the bottle and also prevent any leakage into the tube in which the valvestem fits, at the same time reducing the friction to a minimum, making expansion uniform and insuring a close contact between the valve and the valve-seat in the spout.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

l. In a Siphon-bottle consisting of the top C, provided with an inwardly-extending integrally-formed tube E, havin g an open iiange at its inner end, a cavity or channelsurrounding the tube, of a yielding valve secured in the end of the tube E, provided with a ball or head iitting into a valve-opening in the cavity leading to the spout, and having an extended circular flange and means for tightening the pressure of the valve in the opening consisting ot the cap J, suitably carried in connection with tube E, as to be adjustable within said tube providing a positive means for holding the valve in position.

2. In combination with a Siphon-bottle, the head or top C, having an inwardly-projecting integrally-formed tube E, having an open flange at its inner end, a cavity or channel surrounding the tube, and a valve of the character described, consisting of the ball or head fitting into a valve-opening leading to the spout and having an extended circular liange carried within the tube E, and bearing against the fiange on the tube, of the supplemental tube II, carried within the tube E, and having a ange abutting with the flange of the valve holding the same in position between the iianges of the tubes E and II, preventing any leakage into the tubes, a cap fitting into the tube H, at the rear purposed for adjusting the pressure of the spring `upon a washer on the valve-stem, making a positive pressure upon the valve and insuring its close contact with the valve-spring in the spout, and a lever L, pivoted to an arm extension from the top piece and carried through an opening in the casing and inserted in the slot in the valve-stem for drawing liquid from the bottle, all substantially as described and shown.

In testimony whereof I affix my signature in presence of two witnesses.

' EMIL SINGER.
